IM-PRO'VED DIE ,FOR FORGING- FRENCH CLIPS FOR CARRIAGES.

The Schedul..l referred to in these Letters Patent and making part of the same.

To all whom ,it muy concernr ,A

Be it known that 1, F. B. MORSE, ot'Piantsvi1le,in theconnty of Hartford, and State ot' Connecticut, have invented a new Improvement in Dies for Forging French Clips for Carriages; and I do hereby declare the following, when taken in connection with the accompanying drawings, and the letters of reference marked thereon, to be a full, clear, and exact description of theusame, and which said drawings constitute part-of this specification, and represent, in-

Figure 1, aperspective view of the upper die in- Figure 2, a perspective View ofthe lower die.

Figures 3 to 10, inclusive, illustrate the operation of the dies. y

This invention relates to an improvement in tbrging the clip known to the trade as the French carriageelip, commonly used on coaches and large carriages.

Heretofore, the clips have been fin'ged by blending, and striking them up into form, in lwhich processit is not only difficult to perfectly form the angles, but' when done, the work is not as good as if the forging had been done without bending the metal. vBy my process, the bending is entirely avoided, and, consequently, a better clip produced; and

The invention consists in a succession of dies, constructed so that the first operation upon the-thitor square bar of metal partially forms the clip, then the blanks transferred to succeeding dies, `until in the fourth o1' lastl the clip is completed. v

To enable others skilled in the art to construct and use my invention, I will proceed to describe the saine as illustrated in the accompanying drawings.

A is the lower, and B, the upper die-block, the meeting-surfaces wrought the required forni, to operate upon the metal in thevfollowing manner:

First taking a dat, straight bar of heated metal, it is placed into the first die, a, recesses 1 1,'formed in the lower die, and corresponding recesses, 2 2, in the upper die, with a plunger, 3, between each, and a centrai recess, 4, the metal is struck into the form devand 8.

noted in` iigs. 3 and 4, the plungers tbrniing the recesses 3 3. Then the blank thus far formed is placed in the second die, b, prqiections 5 setting into the recesses 3 3 in the blank. In the upper die, two plungers, 6 6. strike upon the blank, upon its edge, and form indentations 7, as sccn in 5 and b'.

Then the ends of the blank, from the recesses out, are drawn down, as denoted by broken lilies, figs. 5 and (i.

Then the blank is placed into the first-trimming die, fig. 12, so that the recess 3 will lie over the projection 8 in the die, fig. 12.

Then the upper part of the die, with a correspondingl recess, Si, strikes down, and cuts `pnt the tin between the two recesses 3 3, so that the blank can be set into the die c, over the bar 1U. 'lhcu the corresponding die in the upper part strikes down upon the blank, bringing it into the forni denoted in figs. 7

At this state, there will probably be some surplus metal, forming iins around the edge ot' the central part of the blank. To trim these i'oln the blank, it is placed into the die, sce fig. 1 4, and the follower, iig. 13, dropped thereon, and the blank trinnued.

Then the blank is placed into the fourth die, d, the bar 10 at that point heilig ofthe proper form and size for the inner angle of the clip, and the upper die ot' `the desired form for the outside ot' the clip, and the upper die being struck upon the-blank in the lower die, forms and finishes the clip; but during the operation of finishing by the dies, it isnt/.times necessary to trim the iin or surplus metal from the clip, which is done by the dies, 13 a'nd 14.

Thus l construct a clip without bending the metal, so that no part ot the metal is overstrained, but, on

the contrary, is consolidated so as to b e much stronger the ordinary process t'or making such Witnesses A. J. Trrrs, MICHAEL RYAN.
